LUBBICATING DEVICE.

siding at Houston, in the c ounty of Harris and State of Texas, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification.

This invention relates to a new and useful improvement in a lubricating device:

The object of the invention is to provide a device of the character described which is designed particularly to be usedV for the purpose of supplying a lubricant to the 'ournal boxes of cars, particularly railway and street cars. l'

Another feature ofthe invention resides 4 in the provision of a device of the character described whereby a fixed amount of the lubricant may be discharged into each journal box thereby preventing an over and consequent waste.

A further feature of the invention resides in the provision of a means for forcing the lubricant out of the device thereby facilitating the operation of applying the lubricant to theboxes.

With the above and other objects in view, the invention has particular relation to ceif tain novel features of construction, operar..

tion and arrangement of parts, ali-example of which is given inthis Vspecfifieatioii and illustrated 'in the accompanying drawings.;y sectional side elevawherein theffrgure is tion of the devices Referring ,now niore particularly( to the drawing, wher'ein like numerals fofldrefer'- ence designate similar parts in eac`n' th'e figures, the numeral 1 designates anloil can lwhich has the bottom 2, one side of said bottom having' 'a depression or recess 3. The top of the can has an inwardly extending annular rim 4, said rim having a suitable orifice 5, surrounded bya bushing 6, which is xed to the flange 4, and into which the plug 7 is threaded. When it is desired to fill the can this plug may be removed. The inner edge of the flange 4, is turned over and threaded and a,4 circular top 8, is provided whose rim is turned downwardly-'and externally threaded so that said top may be screwed into the down-turned portion of the flange 4, and the can thus completely closed.

Centrally located in the can 1 and fixed to the bottom thexeof, is the pump cylinder 2.), is

Specification of Letters Yatent.

lrun u and t e range rif-movement of the piston' piston is iixed to the lower end of the piston rod 11, which extends upwardly through the central orifice 12, of the top 8, and the upper end of thepiston rod vhas fixed'thereto a knob or gri 13. A flat bail 14, is provided which is Xed to the sides of the can in any well-known manner and the piston rod 11, extends up through an alined orifice in the top of said bail. A collarl, is provided which'extends through the orice in said bail and has an annular iange which engages against The upper end of this collar carries the grip or handholdl, which is iixed to said collar.

Fixed upon the piston 11, underneath the collar 15, is a flange 17, and interposed between said lange and the top 8, and surrounding the piston rod is a strong coil spring 18, which normally holds the piston rod and the piston elevated. Surrounding the orifice 12, is an upstanding funnel shaped iange 19, which is provided to catch 'vali-fes numbered respectively 20 and 21 and rilztnged on opposite sides of said cylinder.

, T e intake valve 20 controls an intakeii'pipe 2.2, which leads into the pump cylinder-9,` land this intakepipe is flared at its freeiend 24 which` leads from said cylinder an pa'sse's up through the ange 4, said outlet pipe having the lock nut 25, screwed thereon to prevent any leakage from the can around said pipe. The numeral 26, refers tothe outlet spout which is attached to the upper end of the pipe 24, by means of elbow 27. This spout may be formed into any shape so as to be suitable for applying a lubricant to any ,style of journal. l

The upper end of the piston rod is outwardly threaded and is provided with two nuts 28, 28, which are threaded on said piston rod and which are intended to lock against one' another. These nuts may be or down'on saidA threaded section thus fixed and the amount of lubricant discharged with each stroke of the piston thus determined. e

The operation of the device is as 'follows z-The can 1 is first filled with a lubri the under side of said bail.

y into the recess l '3. -Thebutlet valvefcntrols the outlet pipe w cant. The resistanceofthe spring l8r'apertiV ating' against the iplange 17, keeps the piston elevated and the cylinder 9, filled with lubricant. il hen it is desired to discharge the lubricant into a journal box the i'nanipnlator may grasp the grip ifij with his fingers and force the knob 13, downwardly until the nnte eiigage against the grip if). This will force the piston l0, downwardly in its cylinderj will close the valve 2li., open the 'valve 2l and drive the iiil'irieast up through t' e pine 24', and-ont tl'irong'h the spout 26., when 'he knol) 137 released, the spring i8, wil operate to elevate .the piston rod and piston which' will close the valve 2l open 'the valve 20 and fili the cylinder f) with .lubricant through, theintalie pipe Ey reason of the fact that the Afree end ot the intake pipe extends into the recess Z3, said thee end will sulnnerged in the lubricant until. the con has become completely empty.

"il-liile have shown only one forni of this device it is olii/ions that the mechanical t iciznre thereof may he changed without reporting from the principle oi the. inven- "l n., an` hereby reserve the right to make such changes in the mechanical, Structure i, wayne ing a container, a removable top therefor having a central orifice, a funnel shaped flange fixed to the top and surrounding said orifice, a bail fixed to the container and having an orifice in alinernent with the central orifice of the ton, a cylinder within the container and 'fixed to the bottom thereof, a fpistiin in said cylinder, a piston rod to the inner end of. which the piston is fixed and which extends out through said orifices, a, knob fixed to the `upper end or' the rod, a resilient member surroundiner said rod, one end of which is attached to the rod and the other end of which rests against said top, a, collar surrounding theV rod one end of which is fixed to said hail a grip fixed to the other end or". said collar, a discharge spout leading from said cylinder, an inlet spout leading into saidl cylinder and having its outer end flared and curved downivardly and means for controlling Said discharge and inlet spout. v

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
